question

Hello ladies. My quad test came back positive with 1:257 and we went to see a specialist. He said the radius of the head was measuring small, but we already decided against an amnio. When we went in for our 20 week u/s, she also said head measuring small, but she could find a nasal bone. I go back to specialist in 8 more weeks for 30 week u/s and am now nervous. I originally thought that the specialists tech may have been off. This is my fourth baby and wondering if I am crazy to worry, or if I have a valid point to be concerned. Any info would be appreciated. Thanks for letting me hop over to your group.

The head measuring small is a very soft marker I believe. The nasal bone can be a marker but our lo had a nasal bone on the ultrasound and does have DS. But your odds are pretty good so I would not be too concerned. Babies with DS can have clear ultrasounds so it's hard to say but I'm thinking your baby is fine.

FWIW, our lo's limbs were measuring smaller so I think they look at that more than the head but I could be wrong. Our baby's head has always been within "normal" range.
